What Are My Rights and Responsibilities After the Permit is Approved?
A permittee who has submitted an NOI and received permit coverage has the duty to comply with all provisions of the general permit and applicable rules and regulations. Coverage under the NPDES general permit does not relieve the permittee of the responsibility for damages to surface or ground water. The permittee must notify the Division as soon as possible of planned alteration or additions to the permitted facility or of any change in mailing address. The permittee is responsible for monitoring discharge, reporting data, keeping records, and placing signs at discharge outfalls as detailed in the general permit. If the facility experiences any emergency that could impact the waters of the state, they must notify the Division as detailed in the general permit.
What Are the Divisions Rights and Responsibilities After the Permit is Approved?
The Division has the right to revoke, suspend, or deny the issuance of a permit to any applicant who violates the state statutes, departmental regulations, or terms of the general permit. The Division has the right to inspect the site, monitoring equipment, and associated records at reasonable times. They also have the right to sample any discharge. Any person who violates or fails to comply with the state statutes, rules, or regulations may be subject to criminal and/or civil penalties.
